Hi I have solved an ODE using NDSolve, and I plot the solution like this: ParametricPlot[{z[t], z'[t]} /. solution, {t, 0, 2 maxTime}, PlotRange -> {{0, 0.2}, {0, 450}}, AspectRatio -> 0.75] The curve shown (the velocity as a function of position) I want to use in a new mathematical expression. How can I do that? If I use z'[t], then it is as a function of time, which is no good to me. I appreciate your help. Best regards, Niles.
